123 Cal is a calorie and protein tracker for iPhone and Apple Watch, operated by Bogdan Dzhelmach ("we", "us"). This policy explains what the app does with your information. It is written to describe the app as it actually works, not as a generic template.
The short version: 123 Cal has no accounts and no login. Your food diary, your photos, and your body measurements stay on your device. A meal photo leaves your phone only at the moment you scan it, purely so it can be estimated, and it is not stored on our servers afterwards. We never sell your data and we never use your Apple Health data for advertising.
Deleting the app removes all of this. You can also erase your diary at any time from Menu → "Delete all logged meals".
When you scan a meal, the photo (or the text description you typed) is sent over an encrypted connection to our processing service, which forwards it to OpenAI's API to produce a nutrition estimate. The estimate comes straight back to your phone.
Apple Health integration is entirely optional and off until you turn it on and grant permission.
Health data is processed on your device only. It is never sent to our servers, never shared with third parties, never used for advertising or marketing, and never used for any purpose other than showing you your own information inside 123 Cal. You can withdraw access at any time in the iOS Health app under Sharing → Apps.
We use Mixpanel to understand how the app is used so we can improve it. Mixpanel receives events such as which screens were opened, that a scan was started, that a meal was logged (including its calorie count), and that a subscription was purchased — along with your device model, operating system version, app version and a randomly generated identifier for your installation.
Mixpanel never receives your name, your email address, your photos, your Apple Health data, or the contents of your food diary beyond the calorie count of a logged meal.
Subscriptions are sold and processed by Apple. We never see or receive your payment card details. We use Superwall to display and manage subscription offers; it receives your subscription status and basic device information so it can show the correct screen.
Our processing service runs on Cloudflare's global network. Nutrition estimation is performed by OpenAI, and analytics by Mixpanel; both are based in the United States. Where personal data is transferred outside the EEA or UK, it is covered by Standard Contractual Clauses or an equivalent safeguard.
Diary entries, photos and profile data remain on your device until you delete them or delete the app. Scan requests are not retained by us once the response is returned. Analytics events are retained for no longer than 24 months.
Depending on where you live, you may have the right to access, correct, delete, restrict or object to the processing of your personal information, to receive a copy of it, and to lodge a complaint with your data protection authority (in Spain, the Agencia Española de Protección de Datos). Because most of your data never leaves your device, you can exercise deletion directly in the app. For anything held by our analytics provider, email us and we will action the request.
123 Cal is not directed at children under 13, and we do not knowingly collect their information. If you are under 16 in the EEA, use the app only with the consent of a parent or guardian.
123 Cal provides estimates for general wellness purposes. It is not a medical device and does not provide medical advice, diagnosis or treatment. Talk to a qualified professional before making significant changes to your diet.
If this policy changes materially, we will update this page and revise the effective date above.
